STLS for opportunistic encryption will increase the likelihood that your outbound mail is in fact encrypted. Still not a guarantee.
A large number of major email providers support STLS, so the uptake is better than you might think. A lot of smaller shops don't. How that affects you will really depend on what your mail use patterns are.
And you can always use PGP/MIME or S/MIME. That's increasingly prevalent in corporate networks, though starting from near nil it's still pretty near nil.
